Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
